摘要: One of the most striking human impacts on global biodiversity is ongoing depletion large vertebrates from terrestrial and aquatic ecosystems. Recent work suggests this loss megafauna can affect processes at biome or Earth system scales with potentially serious ecosystem structure function, services, biogeochemical cycles. We argue that our contemporary approach to conservation focuses spatial are too small adequately address these impacts. advocate a new gap, which must enable megafaunal populations recover functionally relevant densities. conclude re-establishing functions needs become an urgent priority for science policy.
